This application is a continuation application of U.S. patent application Ser. No. 13/929,061 filed on, Jun. 27, 2013, which claims the priority benefit of Taiwan Patent Application Serial Number 101124573, filed on Jul. 6, 2012, the full disclosure of which is incorporated herein by reference.

BACKGROUND 1. Field of the Disclosure

This disclosure generally relates to eyeglasses and, more particularly, to glasses with gesture recognition function.

2. Description of the Related Art

With the vigorous development of the smartphone technology, the sensitivity and smoothness of the touch panel are also improved for being operated and used on the users' cell phones. More and more control gestures have been provided such as moving the thumb closer to or farther away the index finger to perform zoom-in and zoom-out functions, or moving the finger rightward to perform a page-turning command. However, the gesture recognition methods mentioned above are all performed through a touch panel.

In the present day, the optical gesture recognition has been developed quickly due to the vigorous development of the multimedia technology. For example, a user can control a smart TV to switch channel or adjust volume by using hand gestures. However, current gesture recognition devices are integrated with the electronic device and the gesture recognition is performed by means of optical sensing such that the operating distance is limited, e.g. the technology disclosed in the U.S. Pat. No. 5,594,469.

It is to be understood that terms of direction used herein, such as upward, downward, leftward, rightward, forward and backward, are only used for reference but not used to limit the present disclosure.

FIG. 1 shows a schematic diagram of the glasses with gesture recognition function according to an embodiment of the present disclosure. Referring to FIG. 1, the glasses with gesture recognition function 100 of this embodiment includes a glasses frame 110, wherein a left lens 122 and a right lens 124 may be embedded in the glasses frame 110. Specifically speaking, the glasses frame 110 includes a left lens frame 112, a right lens frame 114, a connecting part 116, a left temple arm 118 a and a right temple arm 118 b. The connecting part 116 is configured to connect the left lens frame 112 and the right lens frame 114. The left temple arm 118 a is connected to the left lens frame 112 and the right temple arm 118 b is connected to the right lens frame 114, wherein the left and right temple arms 118 a, 118 b are used to support and fix the glasses 100 on two sides of a user's head.

In one embodiment, the glasses frame 110 may have an integrated structure; i.e. the left lens frame 112, the right lens frame 114, the connecting part 116 and the left and right temple arms 118 a, 118 b are formed integrally. The glasses frame 110 of this embodiment is described with an example having a partially integrated structure; i.e. only the left lens frame 112, the right lens frame 114 and the connecting part 116 are formed integrally as shown by the glasses 100 in FIG. 3, but the present disclosure is not limited thereto.

Referring to FIG. 1, the glasses 110 of this embodiment further include a gesture recognition system 130, wherein the gesture recognition system 130 may be disposed on or in the glasses frame 110. For example, the gesture recognition system 130 may be disposed on the connecting part 116 of the glasses frame 110, wherein an example of the gesture recognition system 130 in this embodiment may be embedded in the connecting part 116. In another embodiment, a part of the gesture recognition system 130 may be embedded in the lens frames 112, 114 or the temple arms 118 a, 118 b and the rest part thereof is exposed outside the lens frames 112, 114 or the temple arms 118 a, 118 b. In this manner, the hand waving of a user may not be performed in front of the user and the hand waving may be performed at the left-front or right-front of the user in order not to block the line of sight. In another embodiment, the gesture recognition system 130 may also be hung on the glasses 100 such that users with myopia may directly hang the gesture recognition system 130 on their glasses without using an additional pair of glasses.

In this embodiment, the gesture recognition system 130 may include an image sensor 132 and a processor 134, wherein the image sensor 132 is configured to successively capture images that contain a motion track of the user's hand, and the processor 134 is configured to receive the images and generate a control command C1 according to the motion track of the user's hand as shown in FIGS. 1 and 2, wherein FIG. 2 is a schematic block diagram of the gesture recognition system 130 of FIG. 1.

In one embodiment, the gesture recognition system 130 may include a transmission unit 136 configured to transmit the control command C1 to an electronic device 200 to correspondingly control the electronic device 200, e.g. controlling the ON/OFF of the electronic device 200, zoom-in or zoom-out of the screen information shown on the electronic device 200, the cursor shown on the screen of the electronic device 200, or the page-turning command of the screen information shown on the electronic device 200. In other words, the control command C1 may be an ON/OFF command, a zoom-in or zoom-out command, a command turning to a previous page or a next page, a volume command or a channel-selection command.

In this embodiment, the electronic device 200 may be a display device (e.g. a TV or a monitor), a portable electronic device (e.g. a cell phone or a tablet computer), home appliance or a vehicle electronic device. More particularly, the electronic device 200 preferably includes a receiving unit 210 configured to receive the control command C1. In other words, the glasses 100 of this embodiment may wirelessly transmit the control command C1 to the electronic device 200 to accordingly control the electronic device 200. In this manner, it is able to provide control on the electronic device 200 at a distance therefrom without being limited by a far distance between the user and the electronic device to avoid the condition that the gesture recognition system is unable to detect gestures of the user's hand. It should be mentioned that, in some cases, the user may not want to use the wireless communication due to the electromagnetic radiation and the gesture recognition unit 130 of the glasses 100 may be connected to the electronic device 200 via a cable in another embodiment.

In addition, in order to improve the performance of recognizing the hand motion, the gesture recognition system 130 may further include an illumination device 138, wherein the illumination device 138 is configured to provide a light beam L1 and the image sensor 132 is configured to receive reflection of the light beam L1 reflected from the hand motion of the user and to generate a plurality of images. Similarly, the processor 134 is configured to receive the images and generate the control command C1 mentioned above according to the motion track of the user's hand. In this embodiment, the illumination device 138 may be one capable of providing infrared light, whereas the image sensor 132 may be one capable of sensing infrared light, wherein as there is generally no object between the hand motion of the user and the glasses 100, the gesture recognition system 130 on the glasses 100 is able to recognize the motion track of the user's hand correctly.

In one embodiment, the glasses 100 may further include a switch device 140, wherein the switch device 140 may be disposed on the glasses frame 110 as shown in FIG. 1. Specifically speaking, the switch device 140 may be configured to turn on or turn off the gesture recognition system 130 so as to effectively reduce the power consumption as well as prevent recognition error.

In addition, the glasses 100 of this embodiment may or may not be embedded with the lens 122, 124 according to the preference of the user. In one embodiment, the left and right lens 122, 124 in the glasses frame 110 of the glasses 100 may be corrective lenses, plain glass lenses or lens capable of displaying images, wherein the lens capable of displaying images may include OLED display panel having high transparency as shown by the glasses 100 a and gesture recognition system 130 a thereof in FIGS. 5 and 6. Specifically speaking, as the lens 122 a, 124 b of the glasses 110 a may directly display images, the wireless transmission unit 136 mentioned above may not be implemented in the gesture recognition system 130 a and the processor 134 may directly transmit the control command C1 to the lens 122 a, 124 a to directly control the content shown on the lens 122 a, 124 a.

In another embodiment, the content shown on the lens may also be formed by projection; i.e. the glasses 100 b may further include a projection device 150, wherein the projection device 150 may directly project images onto the lens 122, 124 as shown by the glasses 100 a and gesture recognition system 130 b thereof in FIGS. 7 and 8. Similarly, as the lens 122, 124 of the glasses 100 b may directly show images through projection, the wireless transmission unit 136 may not be implemented in the gesture recognition system 130 a and the processor 134 may directly transmit the control command C1 to the projection device 150 to directly control the content projected on the lens 122, 124.

It should be mentioned that the gesture recognition systems 130, 130 a and 130 b generate the aforementioned control command by using their own processor 134 to process the gesture images received. In one embodiment, the processor 134 may be integrated with the electronic device 200; i.e. the gesture recognition system 130 c may utilize a control unit 131 to transmit the captured image data I1 to the electronic device 200 through the transmission unit 136 and the processor 134 of the electronic device 200 processes the image data to generate the control command C1 mentioned above as shown in FIG. 4, wherein FIG. 4 shows a schematic diagram of the gesture recognition system in which the processor is integrated with the electronic device 200.

As mentioned above, the gesture recognition system and the glasses with gesture recognition function according to the embodiment of the present disclosure have at least following advantages. First, the gesture recognition system has a wireless transmission unit so that the gesture recognition system has an operating distance from the devices to be controlled. As the gesture recognition system may be disposed on the glasses or other portable devices, e.g. a Bluetooth earphone, a cell phone or a tablet computer, it may be placed close to the user all the time. The control command may be transmitted to the electronic device to be controlled through the wireless communication unit of the gesture recognition system to significantly extend the operating distance compared to traditional systems.

In addition, the gesture recognition system may be located at different positions of the glasses so as to improve the gesture operation. For example, the gesture recognition system may be disposed at the connecting part or the periphery of edges so that the gesture operation may have a lower chance to block the line of sight. Furthermore, if the glasses have the display unit for displaying images, the gesture recognition system may not include the wireless transmission unit; i.e. the control command generated by the processor may be directly transmitted to the display unit to accordingly control the content shown on the glasses.

Although the disclosure has been explained in relation to its preferred embodiment, it is not used to limit the disclosure. It is to be understood that many other possible modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the disclosure as hereinafter claimed.
